High-Resolution and Artifact-Free Measurement and Visualization of Tissue Strain by Processing MRI Using a Deep Learning Approach

This technology includes a system for automatic artifact-free measurement and visualization of tissue strain by MRI at native resolution. The investigation of regional soft tissue mechanical strain can serve as a unique indicator for different related disorders. For example, measurement of myocardial tissue during contraction can help calculate, track, and assess cardiac stress. Currently, methods such as tagging MRI (tMRI) are used for imaging soft tissue deformation. Despite being well validated, methods such as tMRI suffer from low spatial and temporal resolution.

Compatible 3-D Intracardiac Echography Catheter and System for Interventional Cardiac Procedures

This technology includes a versatile intravascular 3D intracardiac echocardiography (ICE) catheter that can operate under conventional X-ray and MRI for use during interventional cardiac procedures. The 3D MRICE and custom, GPU-based, real-time imaging system are also included. Structural heart disease affects more than 2.9% of the US population, and common interventional procedures can be difficult because of limitations in catheter devices and inadequate image guidance.

A Machine Learning Strategy to Improve the Fidelity of Imaging Time-Varying Signals to Improve Clinical Imaging

This technology includes a new technique to improve the fidelity of time-varying signals acquired in the dynamic contrast enhanced (DCE) imaging. This technique enhances the time-varying signals in a given DCE image series through deep convolutional neural networks (CNN) to learn the relationship of signal versus contrast concentration from other series of different contrast doses.

Anti-Puromycin Antibodies Illuminate the World of Cellular Protein Translation

The Ribopuromycylation (RPM) technology, developed by Dr. Jon Yewdell and Dr. Alexandre David, offers a powerful and universal method for visualizing and studying protein translation within cells. RPM involves the use of puromycin, a molecule that mimics a tyrosyl-tRNA and terminates translation by becoming covalently incorporated into the nascent protein chain's C-terminus within the ribosome's A site. This technique enables the immobilization of puromycylated nascent protein chains on ribosomes when chain elongation inhibitors like cycloheximide or emetine are utilized.

Replicative-Defective Mutant Human Cytomegalovirus: Potential Applications in Vaccinology and Cancer Immunotherapy

The potential applications of a replicative-defective mutant form of human cytomegalovirus (HCMV) are significant in the fields of vaccinology and cancer immunotherapy. This innovative approach involves engineering a mutant HCMV that can selectively target specific cells. Firstly, it holds promise as a vaccine candidate for protecting against HCMV infection, given the success of a similar strategy against herpes simplex virus in animal models.

Optimizing RSV Infection Monitoring and High-Throughput Screening Through GFP Expression in the First-Gene Position of Respiratory Syncytial Virus (RSV) Strain A2

In this technology, researchers have engineered a modified version of Respiratory Syncytial Virus (RSV) strain A2 using reverse genetics to incorporate green fluorescent protein (GFP) into the first-gene position. This genetic modification allows for the efficient monitoring of RSV infection and the screening of potential chemical inhibitors. The GFP expression can be easily detected through fluorescence microscopy in live or fixed cells, providing a sensitive tool for both research and drug discovery.
